BRASILIA (Reuters) - President Dilma Rousseff has gained support among Brazilian voters and is almost even with opposition candidate Marina Silva, suggesting the runoff that should decide next month's presidential election is too close to call, according to a new poll on Friday.
The Datafolha survey showed Silva with 46 percent voter support compared with 44 percent for Rousseff in a simulation of the expected second-round runoff. The gap has narrowed to two percentage points from four in the previous survey and is a statistical tie because it is within the poll's margin of error.
